I have switched to the Euro Pin system about 5 years ago, after much testing and being certain that indeed this is a better system. However, I have used the mast foot supplied by Fiberspar, which was a similar mast foot to the original Streamlined foot. As of late I have had a rash of pins shearing at the base of the euro pin. This euro pin is a female thread with a male bolt that screws into it. I am alarmed at the amount of bolts that are shearing all of a sudden. After discussing with Dave Dominy of Streamlined, he found the cause is the plastic on the top piece of the imitation mast foot, flexes under load, and pointloads the bolt. With repeated instances, the bolt eventually shears. Blue arrow points to problem area.
Interesting simulations about the mast extensions. What happens, if you put the holes lengthwise, sidewise, or you use “Ring And Collar”.
The highest strain reached, if the force and leverage is the same:
Pin-hole across: 14,94
Pin-hole length wise: 7,97
Looks like we gonne relive the 80’s.Twinzers, quads, funky looking wavesails.
C7: Is it possible to beat the new school fraction with classic wave sailing on classic boards?
Josh Angulo: Maybe I can better answer this afternoon :) If you get a young kid that does all the tricks and put him on a single fin and he’d still do all the tricks, just bigger. I’m surprised how hard the young guys work to make windsurfing even more difficult by the equipment they ride. I see things in waveboard design that boggle my mind at how much it doesnt make sense and the crazier thing is the industry pushes it and then wonders why our sport is thinning out . Give me a board that planes easy, cuts through chop, goes upwind, jumps well, and holds strong in waves……. does anything really beat a cleanly shaped single fin for overall windsurf performance?
